An urea separation device comprising a urea separation column, an activated carbon column, a transparent conduit section with an ultraviolet light source, a flow controller and a filter. The urea separation well contains a material which absorbs urea. The activated carbon serves to adsorb creatinine, uric acid and other toxic substances * The dialysate fluid is sterilized by the ültra violet light source in the transparent tubing section to prevent bacterial growth. * By means of the flow regulator, the dialysate fluid flow is controlled by the device · The constantly flowing flow of the diaiysate fluid is maintained by a fluid pump · The entire device is designed so that it can be carried on the hip by a patient, see page 3. Its disadvantage is that the entire structure is relatively complicated, having a drive device Due to the small amount of dialysate used, approx column and the activated charcoal column are often changed, whereby the risk of peritonitis is increased.

These disadvantages are partially eliminated by continuous ambulatory peritoneal dialysis (GAPD). The dialyzer used for this consists of a peritoneal indwelling catheter, a tubing system and a dialysis fluid reservoir. The dialysis fluid is discharged via the free-fall system into the abdominal cavity of the dialysis fluid Patients introduced, 'While the whereabouts of the dialysis fluid in the abdomen, the actual mass transfer takes place, the peritoneum serves as a dialysis membrane. The Dialysierflüssigkeitsbehälter remains connected to the tube system at this time and is worn by the patient's body ITachca · x 4 - 6 hours, the deep Dialysierflüssigkeitsbehälter is hung f so that the water with '

and the dialyzable substances and poisons enriched dia- lysing fluid can run back into these. The patient removes this D.ialysing liquid container and exchanges it for a new one. Thus, the dialysis patient is practically independent of the clinic, since only the change of the transfer system should be made under clinical conditions. "The advantages der.GAPD are mainly due to the fact that the process similar to the healthy liiere permanently: works and thus large fluctuations. - be avoided in the water and electrolyte balance and throughout the uremic metabolism.

With all these benefits, the possible peritonitis risk should be considered in CAPD treatment. The dialysis fluid container is changed on average four times a day, so that the risk of peritonitis is relatively large.

Aim of the invention:

The aim of the invention is a regeneration system. for one. Dyslexia treatment for developing CAPD, increasing the patient's freedom of movement and reducing the risk of peritonitis as well as reducing the costs of dialysis treatment.

Explanation of the essence of the invention: /

The invention is based on the task of designing the diathering device with a regeneration system in such a way that it is simple in its construction and permits an extension of the dialysis change time.

According to the invention the object is achieved in that the 'provided for Dialysatreinigung Regenerationssystem'innerhalb of Dialysierflüssigkeitsbehälters or is disposed in the tube system and that the individual Segenerationselement from a f 9siren ;, fIfcn aüsgs'bilde'te'n Gihäüseeinherit -or- Removing a 1 flesib -

is formed lenol unit, at whose Mn and output a filter system is arranged.

The regeneration system is advantageously arranged at the inlet and outlet of the dialysis fluid container and connected to the latter. It is also possible for the regeneration system or the regeneration element to be surrounded by a liquid-permeable filter unit and to be freely movable in the dialysis fluid container.

Hachdem the dialysis fluid from the dialysis fluid through the tube system and the dialysis indwelling catheter was introduced into the abdomen of a patient and stayed there for several hours, which is enriched with urea, uric acid, creatinine and other toxic substances and ultrafiltrate dialysis fluid from the abdominal back to the dialysis fluid passed the regeneration system. Urea, cratinine and other toxic substances are bound in the regeneration elements by the adsorbents or ion exchangers, so that again a largely purified dialysis fluid is available. This can now be one or more times supplied to the patient until the adsorbents are consumed in the regeneration elements. It is necessary that a portion of the enriched by the resulting ultrafiltrate dialysis fluid is removed from the dialyzer via an injection adapter * 1 It is also possible '- stoichiometrically to regulate the dialysis fluid about this In.jektionszwischenstück and: to approach medication

Arrangement of the regeneration system within the Dialysierflüssigkeitsbehälters

The dialyzer for a GAPD consists of a Feritonealdialyseyerweilkatiieter-. 1, a hose system 2 with an injection intermediate piece 3 and a dialysis fluid container 4, which is filled to about two-thirds with a dialysis fluid 5 which is conducted via the hose system 2 and the peritoneal dialysis dicer 1 into the abdominal area of the patient. a roller clamp δ the scuba diving system 2 is closed and the dialysis fluid 5 remains for several hours in the abdominal cavity.

JTach Pig · 1, a regeneration system 7 is integrated within the flexible hose system 2. This, .- iie ; generations system ? consists of 'two or more' Regenerätiohselementen 8. The regeneration elements 8 are filled with selective adsorbents or »ion exchangers depending on the necessity of elimination of pollutants from the used dialyzing 5. However, the regeneration system 7 can also be formed only from a regeneration element 8 with a mixture of different adsorbents or »ion exchangers. The regeneration element 8 consists either of a solid, flat housing unit or of a flexible film unit, at the inputs and outputs are each a filter system 10 is used, the fixation of the adsorbents 9 or »ion exchanger within the enclosure during the process of ümspülung or, ensure the flow of dialysis fluid 3 through the regeneration elements. The regeneration elements are firmly connected to the hose system 2, z. 3. by sieving or welding.

In Figo 2, the regeneration system 7 is disposed outside of the dialysis fluid container 4 at its Sin- or outlet, with a direct positive connection between the regeneration system 7? Dialysis fluid 4 and 2 hose system is formed.

3 a and 3 b show the arrangement of regeneration systems 7 within the dialysing fluid container 4. The regeneration system 7 can once be connected directly to the SinbZW, outlet (FIG. 3 a). Secondly, the regeneration system 7 can move freely in the dialysis fluid container 4 are located (3 b). In this case, the regeneration system 7 consists of a liquid-permeable filter unit 11, which encloses the adsorbents 9 or o ion exchanger *
